Antoine equations can only be used with pure components, not with mixtures. Considering ideal behaviour, the vapor pressure of a mixture would be P = P1*x1 + P2*x2 (Raoult's law), where P1 and P2 are the vapor pressures of the two components and x1 and x2 their molar fractions

The Antoine coefficient for mercury is a set of temperature-dependent constants used in the Antoine equation to describe the vapor pressure of mercury as a function of temperature. These coefficients are specific to mercury and are commonly used in chemical engineering and thermodynamics to model and predict the behavior of mercury in various processes.
Antoine coefficients for acetone are A = 14.31479, B = 2756.17, and C = 228.060. These coefficients are used in the Antoine equation to estimate the vapor pressure of acetone over a range of temperatures.
Antoine Lavoisier's father was a wealthy Parisian lawyer named Jean-Antoine Lavoisier. He provided his son with a good education and financial support, which allowed Antoine to pursue his scientific interests.
Antoine Lavoisier, a French chemist, is credited with discovering the chemical composition of water and proposing the chemical equation for its formation in 1783. He demonstrated that water is composed of two elements, hydrogen and oxygen, in a 2:1 ratio.
The Antoine equation for methane looks like: log10(P) = 6.69561 - 405.420 / (T +267.777). P is in mm Hg, T is in degrees C within temperature ranges -181 < T < -152.
Actual vapor pressure can be calculated using the Antoine equation, which is a function of temperature and constants specific to the substance of interest. The equation is: ln(P) = A - (B / (T + C)), where P is the actual vapor pressure, T is the temperature in Kelvin, and A, B, and C are substance-specific constants.

The Antoine coefficients are empirical constants used in the Antoine equation to describe the relationship between vapor pressure and temperature for a given substance. For light naphtha, these coefficients enable the calculation of vapor pressure at various temperatures, which is crucial for processes like distillation and refining in the petrochemical industry. Typically, the coefficients are determined experimentally and can vary based on the specific composition of the naphtha. Generally, light naphtha has a boiling range of about 30°C to 90°C, and its vapor pressure characteristics are essential for safe handling and processing.
The Nation Institute of Standards and Technology web site has the figures Note there are three coefficients - the Antoine equation gives a reasonable fit to vapour pressure.
The Antoine coefficients for isobutane in the temperature range of -83°C to 7°C are A=13.8254, B=2181.79, C=248.870. These coefficients are valid for Antoine's equation in the form of ln(Psat [kPa]) = A - B/(T[°C] + C). (Source Introduction to Chemical Engineering Thermodynamics 7th ed by J.M. Smith, p.682)
